Note-A-Rific: X-Rays Uses of X-rays X-Rays, which were discovered by Wilhelm K. Roentgen , have several uses° They are now most commonly used as a diagnostic tool to make x-ray images. In some cases they are used to fight some types of cancer. They are also used to study the crystal structure of solids, since their wavelength is about the same size as the spacing between atoms. Unfortunately, X-Rays have high enough energies that they can damage and destroy living tissue, so exposure to them must be limited. Producing X-Rays X-Rays are produced when accelerated electrons strike a (typically) metal target. They can collide with atoms of the material giving up most of their energy as heat (about 99%, so x-ray tubes must be cooled.) and the rest as a photon The electrons sometimes slam right into the atoms of the material and throw off the x-rays. Sometimes the electrons just ±skid² past the atoms, moving in a curve° o Since any curved motion is an

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
